MathematicsEasy63×since 2002Q3659Let f : R →\to→ R be defined as f(x)=x3+x−5f(x) = {x^3} + x - 5f(x)=x3+x−5. If g(x) is a function such that f(g(x))=x,∀′x′∈Rf(g(x)) = x,\forall 'x' \in Rf(g(x))=x,∀′x′∈R, then g'(63) is equal to ________________.A149{1 \over {49}}491B349{3 \over {49}}493C4349{43 \over {49}}4943D9149{91 \over {49}}4991Check answerSkip
